Organic Chemistry Stereochemistry Help Needed!

Hi guys, so I'm having all sorts of problems with Stereochemistry.. we learned this like a month ago but I never got the hang of it and now our professor is just spitting out reactions and all the questions are "indicate the products of this reaction. include stereoisomers."

Can you guys teach me your way of doing stereochemistry or refer me to a good website that teaches stereochemistry? I've read the stereochem chapter in my book 3 times and i've went online to some websites but the more I try to learn it, the more confused I am.

Thank you.🙂

look at your right and left hand. They are very similar, but the relative placement of various things is different as evidenced by the fact that you cant usually wear a left hand glove on the right hand (unless its specially designed for it)

try this website

Well, it would help if you told us what exactly is confusing you.

What specifically do you have problems with? Certain reactions are stereospecific and the professor just seems to be reminding you to include proper stereochemistry (Sn2 inversion for example). Stereochemistry is so broad that "teach me it" isn't going to get you the answers you're looking for.

telling whether two molecules given in perspective formula, fischer projection, or newman projection are enantiomers, diastereomers, identical or meso.

watch my video then!
